Recommended Dosage of Magnesium for Horses
Determining the appropriate dosage of magnesium for your horse depends on various factors such as age, weight, and activity level. Typically, horses require between 7.5 to 15 grams of magnesium per day. However, it’s essential to consult with a veterinarian to tailor the dosage to your horses specific needs.
